To all whom it may concern:

Be it known thatI, JOHN A. ANDERSON, a citizen of the United States ofAnierica,--re-r; sidingat Osage City, in the county of Osage and Stateof Kansas, have invented new and useful Improvements in Feeders andBandCutters, of Which'the following is a specificatiou'. t The inventionrelates toself-governing feed- 1 o ers (incl uding the band-cutters) forthreshing machines; Whileintended for all kinds of wgrain, the machineherein described isfespeeially,adaptable.for wet ordamaged grain.

The general object is to improve such de- VlC6S.,-- i The more specialobjects are to provide a governing-mechanism whereby the feeder may begoverned by the strain on the main driving-belt of the separator'that isto say, by 2 the load instead of by the speed'so that when any part ofthe separator becomes clogged or overloaded the feeder will slow uho'rstop until the clogging or overload has been reduced. Eu rther objectsare to providefeed blades and 5 connections which more regularly feedas'well' as retard the straw or other material thrashed; to providegoverning apparatus for controlling the carrier. ()ther special objectswill be explained more-in detail hereinafter. 3 The invention consistsof the novel combination, arrangement, and disposition, of the parts,the preferred form' of theembodiment whereof. is'shown'and described inthis specification and also shown in the accompanying drawings, formingpartof this specification.

"shaft 17, suitably mounted in the boxing 'l igfl on top of the frame,is keyed therod 19,- car z normally quite low against thepull'ing partof against the same by the springfiL'attached to- 1 the lugaa on theframe." At the other end ofthe shaftl'iis keyed the rod 22.; Pivoted tothe stud- 24, projecting from the frame,

. l3; l1, driven by the engine-driver 1'2. ll lieshaftf the arm or lever'25, carrying the pulley 26,

" which bears against the slack side of the belt 15, connecting pulleys14 and 16. The levers 23 and 25 are connected bylthe rod 27 and nut 28,whereby the, connection may be adjusted, and the pulley 26 is heldfirmly against the drive belt by the spring 29. It is noticed that thepulleys and 26',- with their connections, act.as belt-tighteners for thebelts 11' and 15. Normally the spring 29 is strong enough to hold pulley26 firmly enough against belt 15 so that the belt will not' slip; but as.the separator, or any part thereof driven by the main drive-belt,becomeschoked and thestrain on said beltxbecomes greater, therebystraightening said-belt againstthe pulley 20 I I and raising it, thepulley 26 will also be raised by, the action of lever 19, shaft 17,lever 23,

rod 27, and lever 25,- thereby permitting the belt 15 to become moreslack, so as to permit it to slipsomewhat' on its pulleys, therebyslackening the feed. When the strain on the main drive-belt becomes verygreat, -the pulley 26 may be thrown entirely out of contact -with thebelt- 15, thereby loosening it to such an extent as to permit the beltto slip without operating the pulleys, thereby stopping the feedmechanism until the strain or overload is reduced. It is understood, ofcourse, that,

if desired, the pulleys 20 and '26 and/levers 19 and instead of havingsprings maybe suitably weighted so as to be drawn tightly" against thebelts 1'1 and 15. In either case, ,however, it will be Seen that thebelts when equipped withthe yielding tighteners form,

"aspring or yielding connection between their respectivepulleys. v .Thepulley 16, through the apparatus hereinafter .to be described, operatestheshaft30,

l inder'.

which-is provided with a series 'of cranks 31 31, radiatingtherefrom indifferent directions,

on which are mounted the upper ends of the knife-bars 32 32, whose lowerends are mounted on a shaft 33, provided with crankscorre fsponding andsimilar'to those on theshaft 30. -The shaft33is operated-bythe'knife-bars 32 .32, and as these' are mounted on the cranks radiatingfrom theshafts 30 and 33 in difler-.

ent directions, as shown, there can be no dead-center of ,the shaft 33.The knife, bars 32 32 incline downwardly toward the cyl- Their upperends, which are curved upwardly, as shown, areprovided with the knivesadjacent to the exit. end of the carrierto cut'the bands thoroughly, andtheir lower ends. areprovided with feed-blades 36 36,

which graduallyincrease in length toward the cylinder, except that thelast ones are shorter in order to conform somewhat to the circumferenceof the cylinder, so as to eflect a thor-.

ough and complete feed of the straw to the cylinder. By this arrangementof the feedblades the straw is properly spread. 37'is the hopper-bottom.-As shown in Figs. 1, 2, and 9, the hopper-bottom is loosely mounted,

through boxing 41 41, on the eccentric. 4O of the shaft 38, the otherend being suspended by suitable hangers 99, oneon each side. In Figs. 10and 11 the hopper-bottom is station aryand is provided with a number ofsprocketchains 43 43, which have the-teeth 103, extending from one endthereof to the other and from sprocket-wheels 42 .42, mounted on theshaft 38, which in this case is straightand by which said chains areoperated, t 0 the sprocket wheels 44 44, which are loosely. mounted onthe shaft 45. a The sprockets may be provided with suitable tighteners.(Not here shown.) In the first case a number of fishbacks 39' 39 maybeused, one between each pair of. knife-bars, as indicated in Fig. 2. Inthe drawings 0 five knife-,1- bars are shown, and these are soarranged,'as-explained, that while some of them 'are up others are down.The shaft 38 is driven by the sprocket-wheel 46 or byv pulley 47 andthecarrier 48, through its shaft 49, is driven by the sprocket-wheel 50.

These two sprockets 46'and 50 are driven by d the sprocketfwheels 51 and52, v(hereinafter to be described,) respectively, and the sprocketchains53am, 54, respectively, which pass over the idle sprocket-wheels 56 and57 respectively,"which,may be loosely mounted on the shaft 58, suitablyattachedv to the upper part of'theframethe'ebject of the extraidlepulleys being tochang'e thedirection of rotation ofhthe sprockets46 and50. .By observing the relative sizes of the-various sprocket connectionsjust described it will be noted that the travel of the hopper-bottomwill be slower than the travel ofthe knife-bars, thus I serving tospread the bundles forward. This arrangement ofthe various partscombines the advantages of'both the rotary and reciprocating motion infeeding apparatus. I

--The shaft 33, which carries the lower ends of the knife-bars," has itsends mountedin boxings61 61, attached to the rack'60, engaging thepinion 62 on asuitable shaft in boxing 63,

on the other side of which pinion is the block or key 64, pivoted to theframe by a pin'65 and having teeth to'fengage'the. teeth of the pinion62 and being so located'as to be capable. of beingjturned'into or out ofengagement with the pinion, as indicated, to hold the pinion, rack,boxing, shaft, and lower ends of the knife-bars in any position to whichthey maybe adjusted; The block 64 is held in place by a pin'66. Thebackiof the rackslides against the frame 68, and the frame in able, soas toplace therein the contained parts hereinafter described. Thispulley contains two governorsfirst, a speed-governor to start the feedapparatus when the separating apparatus has attained threshing speed andto stop it when the separating apparatus falls below that speed, and,second, a governing device to regulate the carrier according to the loadon the feeding driving mechanism;

In relation to" the speed-governor this is Y much. similar to otherdevices in use. The

. levers 72, pivoted tolugs 7 3 on the outer ipul- IO ley 16, areprovided with weights slidably se-- cured thereon by'thumb-screws 7 5.To the other arm of .the lever 72-is attached the belt 76, whichpartiallysurroundsthe innerpuL ley 71 and whose other end is attached tothe lug 77 on the pulley 16, which lug 77 also serves to limit-theinward movement of the weight-arm of the levers'72 against the pressureof the springv 7 9; I Normally the spring 7 9 forces theweight arm ofthe leverv inwardly,

so as to slacken the belt 76; but as thepulley is revolved thecentrifugal force throws the weight-arms outwardly, so as to draw the 7belt or band 76 tightly against the peri phery of the inner pulley 71,so as to frictionally-en- 7 5 gage thersame,'causing it to revolve withthe outer, pulley. Thev parts are to beso constructed and adjustedthat'u'pon the outer pulley arriving at threshing speed the weights willbe thrown outwardly sufiiciently to cause 3 the bands76jto engage theinner pulley and to release the same when the outer pulley runs slower.The pulley -71 is operatively connected to the shaft by thelugs 82 82;,

a springs 83 83, arms 8181, and, hub 80, keyed to the shaft 30. Thesprings 83 83 form the spring connection between the pulley 71 and---theshaft 30. These operative connections with others r'orm the"governing device which will be described in the next-paragraph, The

4 governor justdescribed is a speed-governor andgoverns the speed offthefeeding 'apparatus according to the'speed of the separatorcylinder,while thegovernor about to be de:

- scribed is a strain-goyernoW-and governs the speed of the carrieraccording to thestrain ."on thespr-in'g connection between the driving:

pulley 71 and shaft '30. r

In descri ting the second governohcontained in the pulley 16 I wishftoeliminate the outer 5 -pulley 16 and the governing mechanism de-Jscribed in the last preceding paragraph and to 'referto thepull'ey 71as the outer pulley.

Noneof, the parts ofthe speedgoverning mechanism except the pulley 71are shown in Figs.

55 6, 7 or 8. Within the member 71, which is:

mounted loosely on the shaft 30.,is a .hub 80, from which radiates-anumber of arms 81 81,

. I which are connected to lugs 82 82 onthem- Side of the outerpulley 71by the springs 83 6O 83, v The'hub is keyed or otherwise suitablyattached to the shaft 30, A sleeve 84 ex-j \tends from the hub of thepulley 71 and has mounted. thereon a sprocket 51, whichmaybe bolted or.keyed, or otherwise suitably secured 5 thereto. Omthe other side, of theweb or,

' spokes of the pulley 71 (the side oppositethat on which the hub 80. islocated) is a disk or pulley 85, which is also providedwith a sleeve,

both disk 85 and sleeve 86 being loosely mounted on the sleeve 84, andthe sleeve'85 has keyed 7 or bolted or otherwise secured thereto asprocket-wheel 52.v Both sprockets have been described as operating,respectively, the hopper-bottom and the carrier.

In Fig. ithe web of the outer pulley 71 is 7'5 partially cut away, asindicated by the line 88, and the disk or pulley 8.5 is-also partiallycut away, as indicated by the line 87,;in order to exhibit the relativepositions of the various parts. A belt or band 89 is connected at one30' end to the lug 90 on the outer pulley 71 and .at the other end tothe lug-91 on the pulley 71 v through the stirrup 93 andspring 92.Normally this belt is adapted to frictionally en-- gagethe periphery ofthe disk or pulley 8,5; 5 but upon the tension of the spring 92 beingreleased the band slackensandreleases its grip upon the disk, therebypermitting the pulley 71 to revolve without the disk. The manner ofcausing the releasing of the tension of the 9 spring 92 is as follows:The lever 94, mounted in and extending through the web or spokes ofthepulley 71, has its inwardly-extending arm connected to onepf-the arms81 by a chain its other arm being attached to the stirrup 95. 93.Morespecifical-ly speaking, the lever 94 consists of theinwardlyvextending arm 96, the

. axle 97-, which forms the fulcrum therefor, and

the outwardly-extending arm 98, as indicated in Fig. 7 The chain 95normally hangs a little slack; but as the increased tension on thesprings 83 83 is c'aused' by the increased load on the shaft 30 suclrslack is takenup and the lever-arm drawn in the direction'thereofpandthe outer arm 96 is'moved against the'tension of the spring 92, therebyloosening the belt 4 or band89, which releases its normal grip onthe-disk 85,,and, vice versa, as the loadis reduced the belt or band 89is again drawn ftightly against the disk 85 by the normal tend- 1 encyof the spring 92. i

In case of breakage or when 1n case of yery good grain it is not desiredto use the'governor 7 last described the springs 83 83 and chain 95 Imay be removed and the arms 81.81 permitted 5 to engage the lugs 82,which may be provided with extensions, as indicated by l0 0 in Fig. 6,thereby locking the pulley 71 and tscontents together just as if it wereasi'ngle piece.

The 'operationof the feeding mechanismiis as follows: The direction ofrotation of the shaft 30 is indicated by the arrow in Fig.

1, from which it will be seen thatwhen the feed or knife blades areinthe lower half ofthe'circle'of rotation they move toward the 5cylinder, while in the upper half theirmotion is inthe oppositedirection. In the motion toward the-cylinder they engage, with thehopper-bottom, the straw and force italong down the hopper to thecylinder. From the pe cul-. 3

ing pushed along therethrough by the operajtion of theffeed-blades andhopper-bottom.-

I The feeding mechanism as a whole is governed by the governor herein'first"descr,ibed,.so that as the separator becomes more orless chokedor overloaded the strain on the drive-belt becomes greater,therebypermitting the belt to slip somewhat, thus slowing up the feeding mechanism, so that no .morestraw will be fed to the cylinder thanthe separator is capa: ble of working. If the separator becomes too muchoverloaded, then, as heretofore ex-' plained, the entire feedingmechanism will A5 stop until the overload is -reduced.- It isunderstood, of course, that the strength of the springs, their tensions,&c., are all subject to being adjusted by the various nuts and otherdevices .used for such purposes. I

71 revolves it carries with itithe' inner hub 80 and shaft by means ofthe springs 83 83, which-connect the pulley 71 to the arms 81 81 of thehub 80. The pulley 71 also causes to revolve with-'it the hopper-bottomshaft 38' through the sleeve 8 42,. sprocket-wheels 51' and 46,andspi'ocket-chain 54,30 that the feed blades and hopper-bottom mayoperate 4 harmoniously. Normally the band88js drawn f tightly-around theperiphery of the. disk by'the 'spring 92, sothatnormallythe said diskrevolves with the pulley flland carries with it the carrier-shaft 49through the sleeve 45 86, sprocket-wheels-52 and-50,'and sprocket-'chain 54. As the loadbetweenthe feed-blades.

and hopper-bottom becomes greater, thereby causing-them to increase thetension on'the springs 83 '83, causingthem to" expandythe" 5 slack inthe chain will be taken up' and the .,lever 94 moved against the tensionof the spring 92, thereby loosening the belt 89 and releasing the disk85, so'that the carrier ,will. stop until the overload inthe feeder-isre..

SSduciedenoughf .to relax the tensionon the springs '83 83 sufficientlyto 'slacken the chain 95, when the belt'"'89 willagain be drawn vtight'by'the spring 92. The'purpose of this peculiar arrangement istogovern the carrier solely by the-load between thef. d-blades andhopper-bottom and'so that wet itraw,'wh ich is quite heavy, maybe'plac'ed on the carrier "withoutstoppingit, as it will be .noted thatthe strain-on the (Farrier-shaft is 'not'borne The operation of the lastdescribed governing mechanism is as follows: As the pulley apparatusbecomes overloaded, then the ca rsa eoo by the springs 83 83, by whichsaid carrier 5 is governed, butby the pulley 71. -Another purpose isthat when used in the form. shown in the drawings the load'on thehopper-bottom shaft 38 does not affect the tension of the springs 83 83,'and consequently does not 7 affect the governing device which contrelsthe carrier-shaft; but if it is desired that the load on thehopper-bottom shall also be included in the governing apparatus then thej chain 54 may be removed and the pulleys 47 '7 5 2 and (see Fig, 9)connected by a suitablebelt,

so that the strain on the hopper-bottom shaft 38, as well as that on thecrank-shaft 30, willr aflect the tension of the springs 83 83, wherebythe carrier-shaft is governed. Theobject in' having this changeablearrangement is to adapt the feeding mechanism to the various kinds ofgrain. I

- Comparatively speaking, the variations I caused by the load in. thefeeding devices will 5 not be sufficient to 'operate the first-describedgovernor, and. the secondand third described .governors will serve tothe feedin'g'apparatus uniform, so that the first governor will becontrolled entirely by the load of the 9 separator. In this manner thefeeding mechanism .as a whole will be governed by the load of-theseparator, while the rack or. carrier will be governed by the load-inthe feeding Y apparatus'without reference the weight on 95 the carrier.i

It is now seen that by the arrangement herein described the feeding ofthe straw into the cylinder may be nicelygoverned not only according tospeed, but also'according to the loo load. Thus if the separator becomesover-' loaded the first-described governor will cause the feedingapparatus and carrier to slow up or to stop. If the engine drives thecylin- 4 der below threshingspeed, thesecond :de- 5' scribed gOVBIfi-Plwill cause the 'feeding ap-j rier-to stop If the feedin paratus and crier will be caused to slow. up. or to stop by reason of the operationof the third-described I 10 'gevernor.

It should also be. noted that an overload on .the carrier does notaffect the springs ,83 83, so that even though the carrier be loadedwith wet and heavy straw the third.- a described governor will not beaflected there-k I 5 by, but-the carrier'will be governed entirely bythe loadin the feeding apparatus.

as having solid webs. It, will be 'unders 00d, of course, that they' mayhave spokes.- hile I have shown the pulley 16 as having a double I Inthe dr'awingsI have shown the pulleys L'- -web, it may be provided witha single web or.

a single set of spokes with a rather large hub. Ihave shown' the aboveforms of my inven-i =tion as illustrating the'prin'ciples thereof and 5do not intend to .limit myself unduly to the peculiarities ofform orconstruction, but contemplate all suitable changes of form orconstruction," proportions, and the substitution ..of equivalent membersas" may be desirable 1 and necessary.
